A novel actinomycete, strain W6T, was isolated from a soil sample of Yunnan Province, China. The bacterium was aerobic, non-motile, non-spore-forming and Gram-stain-positive. Genetic, phenotypic and chemical properties of the isolate were studied. 16S rRNA gene sequence data suggested that the novel isolate belonged to the genus Friedmanniella and shared 98.6 % sequence similarity with Friedmanniella antarctica DSM 11053T and Friedmanniella okinawensis DSM 21744T, the most closely related species. The cell-wall peptidoglycan contained ll-diaminopimelic acid, and mycolic acids were absent. The main menaquinone was MK-9(H4) and the predominant fatty acids were anteiso-C15 : 0 and iso-C15 : 0. The phospholipid profile contained phosphatidylglycerol, phosphatidylinositol, phosphatidylcholine and diphosphatidylglycerol. The DNA G+C content of strain W6T was 72 mol%. Strain W6T showed 30.0 % and 28.5 % DNA–DNA relatedness, respectively, to F. antarctica DSM 11053T and F. okinawensis DSM 21744T. The combined genotypic and phenotypic data showed that strain W6T should be assigned to the genus Friedmanniella as a representative of a novel species, for which the name Friedmanniella flava sp. nov. is proposed. The type strain is W6T ( = CGMCC 4.6856T = JCM 17701T).

Strain H5T was isolated from a sediment sample collected from the coastal area of Qingdao, China. The cells were Gram-stain-positive, non-motile, straight or curved rods. The temperature range for growth was 20–37 °C and the pH for growth ranged from 6.5 to 9.0, with optimum growth occurring in the temperature range 28–30 °C and pH range 7.5–8.0. Growth occurred in the presence of 0–6 % (w/v) NaCl (optimum, 0–2 %). Strain H5T had MK-9, MK-9(H2) and MK-9(H4) as the major menaquinones and C18 : 1ω9c, C16 : 0, C14 : 0, C18 : 0 and C16 : 1ω9c as major fatty acids. The cell-wall peptidoglycan type was A5α l-Lys-l-Ala-l-Lys-d-Glu. The major polar lipids were phosphatidylglycerol (PG), an unknown phospholipid (PL1) and two unknown phosphoglycolipids (PGL1, PGL2). An unknown phospholipid (PL2) and two unknown glycolipids (GL1, GL2) were present in moderate to minor amounts in the polar lipid profile. The genomic DNA G+C content was 61.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain H5T represents a novel lineage in the family Actinomycetaceae . On the basis of phenotypic, physiological and molecular characteristics, it is proposed that the novel isolate should be classified as a novel species in a new genus: Flaviflexus huanghaiensis gen. nov., sp. nov., with strain H5T ( = DSM 24315T = CICC 10486T) as the type strain of the type species.

A novel actinobacterium strain, 2614A723T, was isolated from rhizosphere soil of mangrove plant Acanthus ilicifolius collected at Touyuan, Wenchang, Hainan province, China. A phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 2614A723T formed a distinct phyletic line in the genus Actinoallomurus , the 16S rRNA gene tree sharing similarities of 98.35 %, 98.07 % and 97.86 % with Actinoallomurus spadix NBRC 14099T, Actinoallomurus purpureus TTN02-30T and Actinoallomurus luridus TT02-15T , respectively. Strain 2614A723T contained lysine and meso-diaminopimelic acid in the cell wall peptidoglycan and madurose, galactose and xylose in the whole-cell sugars. The predominant menaquinones were MK-9(H4) and MK-9(H6). The major polar phospholipids were phosphatidylglycerol and diphosphatidylglycerol. The predominant fatty acids were iso-C16 : 0 and anteiso-C17 : 0. These chemotaxonomic data confirmed the affiliation of strain 2614A723T to the genus Actinoallomurus . It is apparent from the combined phenotypic data, biochemical tests and DNA–DNA hybridization values that strain 2614A723T should be classified in the genus Actinoallomurus as a representative of a novel species. The name Actinoallomurus acanthiterrae sp. nov. is proposed with strain 2614A723T ( = CCTCC AA 2012001T = DSM 45727T) as the type strain.

Two novel actinomycetes, strains TA4-1T and TA4-8T, were isolated from the South-East Asian stingless bee (Tetragonilla collina Smith 1857), collected from Chiang Mai Province, Thailand. The morphological and chemotaxonomic properties of strains TA4-1T and TA4-8T were consistent with the genus Streptomyces , i.e. the formation of aerial mycelia bearing spiral spore chains, the presence of the ll-isomer of diaminopimelic acid in cell walls, iso- and anteiso-branched fatty acids with carbon chain lengths 14–17 atoms as the major fatty acids and MK-9(H8) as the predominant menaquinone plus minor amounts of MK-9(H6) and MK-9(H10). Analysis of 16S rRNA gene sequences showed that strains TA4-1T and TA4-8T exhibited 98.8 and 98.1 % sequence similarity, respectively, with Streptomyces chromofuscus NRRL B-12175T and 98.9 % sequence similarity with each other. This study suggested that strains TA4-1T and TA4-8T were distinct from previously described species of the genus Streptomyces . In addition, the low degrees of DNA–DNA relatedness between the isolates and S. chromofuscus JCM 4354T warranted assigning strains TA4-1T and TA4-8T to two novel species. The names Streptomyces chiangmaiensis sp. nov. (type strain TA4-1T  = JCM 16577T  = TISTR 1981T) and Streptomyces lannensis sp. nov. (type strain TA4-8T  = JCM 16578T  = TISTR 1982T) are proposed. The species names indicate the geographical locations where the stingless bees reside.

Six facultatively anaerobic, non-motile lactic acid bacteria were isolated from spontaneous cocoa bean fermentations carried out in Brazil, Ecuador and Malaysia. Phylogenetic analysis revealed that one of these strains, designated M75T, isolated from a Brazilian cocoa bean fermentation, had the highest 16S rRNA gene sequence similarity towards Weissella fabaria LMG 24289T (97.7 %), W. ghanensis LMG 24286T (93.3 %) and W. beninensis LMG 25373T (93.4 %). The remaining lactic acid bacteria isolates, represented by strain M622, showed the highest 16S rRNA gene sequence similarity towards the type strain of Fructobacillus tropaeoli (99.9 %), a recently described species isolated from a flower in South Africa. pheS gene sequence analysis indicated that the former strain represented a novel species, whereas pheS, rpoA and atpA gene sequence analysis indicated that the remaining five strains belonged to F. tropaeoli ; these results were confirmed by DNA–DNA hybridization experiments towards their respective nearest phylogenetic neighbours. Additionally, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry proved successful for the identification of species of the genera Weissella and Fructobacillus and for the recognition of the novel species. We propose to classify strain M75T ( = LMG 26217T  = CCUG 61472T) as the type strain of the novel species Weissella fabalis sp. nov.

A novel filamentous bacterium, designated Nari11AT, was isolated from soil collected from a salt lake named Chott Melghir, located in north-eastern Algeria. The strain is an aerobic, halophilic, thermotolerant, Gram-stain-positive bacterium, growing at NaCl concentrations between 5 and 20 % (w/v) and at 43–60 °C and pH 5.0–10.0. The major fatty acids were iso-C15 : 0, anteiso-C15 : 0 and iso-C17 : 0. The DNA G+C content was 53.4 mol%. ll-Diaminopimelic acid was the diamino acid of the peptidoglycan. The major menaquinone was MK-7, but MK-6 and MK-8 were also present in trace amounts. The polar lipid profile consisted of phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylmonomethylethanolamine and three unidentified phospholipids. Results of molecular and phenotypic analyses led to the description of the strain as a novel member to the genus Melghirimyces , family Thermoactinomycetaceae . Strain Nari11AT shows 96.7 % 16S rRNA gene sequence similarity to the type strain of Melghirimyces algeriensis . On the basis of phenotypic, physiological and phylogenetic data, strain Nari11AT ( = DSM 45514T  = CCUG 60050T) represents the type strain of a novel species, for which the name Melghirimyces thermohalophilus sp. nov. is proposed.

Analysis of the 16S rRNA gene sequences of species currently assigned to the genus Bacillus has shown an extensive intrageneric phylogenetic heterogeneity. The 16S rRNA gene sequence of Bacillus schlegelii ATCC 43741T shows only 82.2–85.9 % sequence similarity to type strains of other members of the genus Bacillus and <88.5 % sequence similarity to recognised species of the most closely related genera, Calditerricola (88.4–88.5 %), Planifilum (87.3–87.8 %) and Caldalkalibacillus (87.2−87.9 %). Furthermore, B. schlegelii ATCC 43741T could not be assigned to an existing family by phylogenetic analysis. The predominant menaquinone was MK-7. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, one unidentified phospholipid and two unidentified glycolipids. The major fatty acids were iso-C16 : 0, C16 : 0, iso-C17 : 0 and anteiso-C17 : 0. Both the polar lipid profile and the fatty acid composition clearly distinguished B. schlegelii DSM 2000T from the type species of the genus Bacillus , Bacillus subtilis . Hence, there is no evidence for a clear phenotypic grouping of this organism into the genus Bacillus nor to the genera Calditerricola , Caldalkalibacillus or Planifilum . A proposal is made to transfer Bacillus schlegelii to a novel genus and species, Hydrogenibacillus schlegelii gen. nov., comb. nov., and to emend the species description. The type strain of the type species is DSM 2000T ( = ATCC 43741T = CCUG 26017T = CIP 106933T).

A species diversity study of lactic acid bacteria occurring in traditional Vietnamese nem chua yielded an isolate, LMG 26767T, that could not be assigned to a species with a validly published name. The isolate was initially investigated by 16S rRNA gene sequence analysis, which revealed that it belonged to the genus Lactobacillus , with Lactobacillus manihotivorans and Lactobacillus camelliae as the closest relatives (98.9 % and 96.9 % gene sequence similarity to the type strains, respectively). Comparative (GTG)5-PCR genomic fingerprinting confirmed the unique taxonomic status of the novel strain. DNA–DNA hybridization experiments, DNA G+C content determination, sequence analysis of the phenylalanyl-tRNA synthase (pheS) gene, and physiological and biochemical characterization demonstrated that strain LMG 26767T represents a novel species, for which the name Lactobacillus porcinae sp. nov. is proposed; the type strain is LMG 26767T ( = CCUG 62266T). Biochemically, L. porcinae can be distinguished from L. manihotivorans and L. camelliae by its carbohydrate fermentation profile, absence of growth at 45 °C, and production of d- and l-lactate as end products of glucose metabolism.

A bacterial strain, designated D75T, was isolated from the rhizosphere soil of Catalpa speciosa. Phylogenetic analysis based on the complete 16S rRNA gene sequence revealed that strain D75T was a member of the genus Paenibacillus . High levels of 16S rRNA gene sequence similarity were found between strain D75T and Paenibacillus glycanilyticus DS-1T (99.2 %), Paenibacillus xinjiangensis B538T (97.5 %) and Paenibacillus castaneae Ch-32T (97.2 %). The chemotaxonomic properties of strain D75T were consistent with those of the genus Paenibacillus : the cell-wall peptidoglycan type was based on meso-diaminopimelic acid (A1γ), the predominant menaquinone was MK-7, and the major fatty acids were anteiso-C15 : 0, iso-C16 : 0 and C16 : 0. However, levels of DNA–DNA relatedness between strain D75T and P. glycanilyticus NBRC 16618T, P. xinjiangensis DSM 16970T and P. castaneae DSM 19417T were 35, 20 and 18 %, respectively. On the basis of phenotypic and chemotaxonomic analyses, phylogenetic data and DNA–DNA relatedness values, strain D75T is considered to represent a novel species of the genus Paenibacillus , for which the name Paenibacillus catalpae sp. nov. is proposed. The type strain is D75T ( = DSM 24714T = CGMCC 1.10784T).

Two Lactobacillus strains, designated LY-73T and LY-30B, were isolated from a dairy beverage, sold in Shenzhen market, China. The two isolates were Gram-positive, non-spore-forming, non-motile, facultatively anaerobic rods that were heterofermentative and did not exhibit catalase activity. Sequencing of the 16S rRNA, pheS and rpoA genes revealed that the two isolates shared 99.5, 99.8 and 99.9 % sequence similarity, which indicates that they belong to the same species. Phylogenetic analysis demonstrated clustering of the two isolates with the genus Lactobacillus . Strain LY-73T showed highest 16S rRNA gene sequence similarities with Lactobacillus harbinensis KACC 12409T (97.73 %), Lactobacillus perolens DSM 12744T (96.96 %) and Lactobacillus selangorensis DSM 13344T (93.10 %). Comparative analyses of their rpoA and pheS gene sequences indicated that the novel strains were significantly different from other Lactobacillus species. Low DNA–DNA reassociation values (50.5 %) were obtained between strain LY-73T and its phylogenetically closest neighbours. The G+C contents of the DNA of the two novel isolates were 56.1 and 56.5 mol%. Straight-chain unsaturated fatty acids C18 : 1ω9c (78.85 and 74.29 %) were the dominant components, and the cell-wall peptidoglycan was of the l-Lys–d-Asp type. Based on phenotypic characteristics, and chemotaxonomic and genotypic data, the novel strains represent a novel species of the genus Lactobacillus , for which the name Lactobacillus shenzhenensis sp. nov. is proposed, with LY-73T ( = CCTCC M 2011481T = KACC 16878T) as the type strain.

Two Gram-reaction-negative, rod-shaped, motile bacteria, designated strains U82 and U95T, were isolated from the marine alga Ulva australis collected at Sharks Point, Clovelly, a rocky intertidal zone near Sydney, Australia. Both strains were oxidase- and catalase-positive, formed brown- to black-pigmented colonies and required NaCl for growth. Phylogenetic analysis based on nearly complete 16S rRNA gene sequences revealed that these strains belong to the Roseobacter clade within the Alphaproteobacteria . The 16S rRNA genes of both strains were identical across the sequenced 1326 nt, but showed differences in the intergenic spacer region (ITS) between the 16S and the 23S rRNA genes. At the genomic level the DNA G+C contents of strains U82 and U95T were identical (52.6 mol%) and they had a DNA–DNA hybridization value of 83.7 %, suggesting that these strains belong to the same species. The closest described phylogenetic neighbour to strains U82 and U95T was Thalassobius aestuarii DSM 15283T with 95.8 % 16S rRNA gene sequence similarity. Other close relatives include further species of the genera Thalassobius and Shimia . Strains U82 and U95T were negative for bacteriochlorophyll a production, showed antibacterial activity towards other marine bacteria, were resistant to the antibiotics gentamicin and spectinomycin and were unable to hydrolyse starch or gelatin. The major fatty acids (>1 %) were 18 : 1ω7c, 16 : 0, 18 : 2, 10 : 0 3-OH, 12 : 0, 20 : 1 2-OH and 18 : 0. The polar lipid pattern indicated the presence of phosphatidylglycerol, phosphatidylcholine, two unidentified aminolipids and four unidentified phospholipids. Both strains produced ubiquinone 10 (Q-10) as the sole respiratory lipoquinone. Based on their phenotypic and phylogenetic characteristics, it is suggested that strains U82 and U95T are members of a novel species within a new genus for which the name Epibacterium ulvae gen. nov., sp. nov. is proposed. The type strain of the type species is U95T ( = DSM 24752T = LMG 26464T).

A novel strain, designated J221T, was isolated from the intestine of a sea cucumber, Apostichopus japonicus, collected from earthen ponds in Qingdao, China. The strain was Gram-negative, oxidase-positive, aerobic, rod-shaped and motile by means of one to several polar flagella. Growth of strain J221T was observed at temperatures between 10 and 40 °C with optimum growth between 25 and 28 °C. The pH range for growth was 5.0–9.0 with optimum growth at pH 7.5–8.0. The dominant fatty acids were summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c, 29.04 %), C16 : 0 (28.93 %) and C18 : 1ω7c (26.15 %). The major polar lipids were phosphatidylglycerol and phosphatidylethanolamine. Diphosphatidylglycerol, an unknown aminolipid and an unknown aminophospholipid were present in moderate to minor amounts in the polar lipid profile. Strain J221T had Q-8 as the major respiratory quinone. The DNA G+C content of strain J221T was 46.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain J221T is a member of the Gammaproteobacteria . It formed a distinct phyletic line with less than 91 % sequence similarity to any species within previously recognized genera. On the basis of this polyphasic taxonomic study, strain J221T should be classified as a representative of a novel species of a new genus, for which the name Neiella marina gen. nov., sp. nov. is proposed. The type strain of Neiella marina is J221T ( = CGMCC 1.10130T = NRRL B-51319T).

A Gram-negative, motile, aerobic, oxidase- and catalase-positive rod, designated P10-2-4T, was isolated from an intertidal sand sample collected from a coastal area of Qingdao (Yellow Sea), China. The isolate reduced nitrate to nitrite and grew at 4–33 °C and with 0.5–12 % (w/v) NaCl. The predominant cellular fatty acids were summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH), C18 : 1ω7c and C16 : 0. The major polar lipids were phosphatidylethanolamine and phosphatidylglycerol. The major respiratory quinone was Q-8. The genomic DNA G+C content was 45.1 %. Phylogenetic analysis of 16S rRNA gene sequences revealed that strain P10-2-4T belonged to the genus Neptunomonas . The isolate shared the highest 16S rRNA gene sequence similarity (98.1 %) with Neptunomonas japonica JAMM 0745T and 96.9, 96.5 and 95.9 % sequence similarities with N. antarctica S3-22T, N. concharum LHW37T and N. naphthovorans NAG-2N-126T, respectively, strains of the other three recognized species in the genus. DNA–DNA relatedness between strain P10-2-4T and N. japonica JCM 14595T was 35.6 %. Furthermore, strain P10-2-4T could be distinguished from the representatives of the genus Neptunomonas by a combination of phenotypic characteristics, such as temperature and NaCl concentration for growth, nitrate reduction, DNase activity and assimilation of substrates. The data from this study suggests that strain P10-2-4T represents a novel species in the genus Neptunomonas , for which the name Neptunomonas qingdaonensis sp. nov. is proposed. The type strain is P10-2-4T ( = CGMCC 1.10971T  = KCTC 23686T).

A Gram-negative, non-spore-forming, non-flagellated, coccoid-, oval- or rod-shaped strain, designated M-M23T, was isolated from seashore sediment at Geoje island, South Korea. Strain M-M23T grew optimally at 25 °C, at pH 7.0–8.0 and in the presence of 2 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences revealed that strain M-M23T clustered with the type strains of the two species of the genus Hirschia , with which it exhibited 97.6–98.1 % 16S rRNA gene sequence similarity. Sequence similarity with the type strains of other recognized species was <90.8 %. Strain M-M23T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c and C16 : 0 as the major fatty acids. The major polar lipids of strain M-M23T were phosphatidylglycerol and two unidentified lipids. The DNA G+C content of strain M-M23T was 45.4 mol%. DNA–DNA relatedness between the isolate and Hirschia baltica DSM 5838T and Hirschia maritima JCM 14974T was 22±7.2 and 14±5.6 %, respectively. The differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain M-M23T is separate from the other described members of the genus Hirschia . On the basis of the data presented, strain M-M23T is considered to represent a novel species of the genus Hirschia , for which the name Hirschia litorea sp. nov. is proposed. The type strain is M-M23T ( = KCTC 32081T  = CCUG 62793T). An emended description of the genus Hirschia is also provided.

Gram-negative bacteria of the genus Xenorhabdus exhibit a mutualistic association with steinernematid entomopathogenic nematodes and a pathogenic relationship with insects. Here we describe two isolates of the entomopathogenic nematode Steinernema aciari collected from China and Japan. 16S rRNA gene sequence similarity and phylogenetic analysis indicated that the isolates obtained from S. aciari belonged to the genus Xenorhabdus . Multilocus sequence analysis based on five universal protein-coding gene sequences revealed that the isolates were closely related to Xenorhabdus ehlersii DSM 16337T and Xenorhabdus griffiniae ID10T but that they exhibited <97 % sequence similarity with these reference strains, which indicated that the isolates were distinct from previously described species. Based on these genetic differences and several differential phenotypic traits, we propose that the isolates represent a novel species of the genus Xenorhabdus , for which we propose the name Xenorhabdus ishibashii sp. nov. The type strain is GDh7T ( = DSM 22670T  = CGMCC 1.9166T).

Four orange-pigmented isolates, L7-456, L7-484T, L9-479 and L9-753T, originating from surface-sterilized leaf tissues of Jatropha curcas L. cultivars were characterized using a polyphasic taxonomic approach. Phylogenetic analyses based on 16S rRNA gene sequences indicated that all four isolates belong to the genus Aureimonas . In these analyses, strain L7-484T appeared to be most closely related to Aureimonas ureilytica 5715S-12T (95.7 % sequence identity). The 16S rRNA gene sequences of strains L7-456, L9-479 and L9-753T were found to be identical and also shared the highest similarity with A. ureilytica 5715S-12T (97.5 %). Both L7-484T and L9-753T contained Q-10 and Q-9 as predominant ubiquinones and diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylmonomethylethanolamine, phosphatidylethanolamine, phosphatidyldimethylethanolamine, sulfoquinovosyldiacylglycerol and an aminophospholipid as the major polar lipids. C18 : 1ω7c and C16 : 0 were the major fatty acids. Similar to other species in the genus Aureimonas , hydroxylated fatty acids (e.g. C18 : 1 2-OH) and cyclic fatty acids (C19 : 0 cyclo ω8c) were also present. The DNA G+C contents of L7-484T and L9-753T were 66.1 and 69.4 mol%, respectively. Strains L7-484T and L9-753T exhibited less than 40 % DNA–DNA hybridization both between themselves and to A. ureilytica KACC 11607T. Our results support the proposal that strain L7-484T represents a novel species within the genus Aureimonas , for which the name Aureimonas jatrophae sp. nov. is proposed, and that strains L9-753T, L7-456 ( = KACC 16229  = DSM 25023) and L9-479 ( = KACC 16228  = DSM 25024) represent a second novel species within the genus, for which the name Aureimonas phyllosphaerae sp. nov. is proposed. The type strains of Aureimonas jatrophae sp. nov. and Aureimonas phyllosphaerae sp. nov. are respectively L7-484T ( = KACC 16230T  = DSM 25025T) and L9-753T ( = KACC 16231T  = DSM 25026T).

Four novel strains of members of the genus Bartonella , OY2-1T, BR11-1T, FN15-2T and KS2-1T, were isolated from the blood of wild-captured greater Egyptian jerboa (Jaculus orientalis), plantain squirrel (Callosciurus notatus), fat-tailed gerbil (Pachyuromys duprasi) and golden spiny mouse (Acomys russatus). All the animals were imported to Japan as pets from Egypt, Thailand and the Netherlands. The phenotypic characterization (growth conditions, incubation periods, biochemical properties and cell morphologies), DNA G+C contents (37.4 mol% for strain OY2-1T, 35.5 mol% for strain BR11-1T, 35.7 mol% for strain FN15-2T and 37.2 mol% for strain KS2-1T), and sequence analyses of the 16S rRNA genes indicated that those strains belong to the genus Bartonella . Sequence comparisons of gltA and rpoB genes suggested that all of the strains should be classified as novel species of the genus Bartonella . In phylogenetic trees based on the concatenated sequences of five loci, including the 16S rRNA, ftsZ, gltA and rpoB genes and the ITS region, and on the concatenated deduced amino acid sequences of three housekeeping genes (ftsZ, gltA and rpoB), all strains formed distinct clades and had unique mammalian hosts that could be discriminated from other known species of the genus Bartonella . These data strongly support the hypothesis that strains OY2-1T, BR11-1T, FN15-2T and KS2-1T should be classified as representing novel species of the genus Bartonella . The names Bartonella jaculi sp. nov., Bartonella callosciuri sp. nov., Bartonella pachyuromydis sp. nov. and Bartonella acomydis sp. nov. are proposed for these novel species. Type strains of Bartonella jaculi sp. nov., Bartonella callosciuri sp. nov., Bartonella pachyuromydis sp. nov. and Bartonella acomydis sp. nov. are OY2-1T ( = JCM 17712T = KCTC 23655T), BR11-1T ( = JCM 17709T = KCTC 23909T), FN15-2T ( = JCM 17714T = KCTC 23657T) and KS2-1T ( = JCM 17706T = KCTC 23907T), respectively.
